we need to connect 80pin SCA Ultra320 SCSI hdd to 68pin on host adapter. The adapter we got is Assmann ABSCA-2. Hard drive is 'Fujitsu MAW3073NC'
we have two 68pin cables, one with and one without the terminator on end. which one to use?
it is essential the drive doesn't get damaged.
Has anyone successfully used an Adaptec 2100S in a RAID configuration? Specifically, RAID1?
Drivers exist for earlier version of Red Hat, but building an using a driver disk results in the error:
Driver disk is invalid for this release of CentOS
CentOS does not recognize the adapter out-of-the-box as a HW RAID controller, but does recognize the individual disks.
I attempted to use software RAID, but the installer craps-out after a while and the screen locks up.
In /proc/scsi/scsi, we can see the scsi host no. (scsi identifier no.). for e.g. Host: scsi4 Channel: 00 Id: 01 Lun: 00 In above e.g., scsi identifier no. is 4. Whenever we modprobe a particular module associated with scsi devices, we can see new entry in/proc/scsi/scsi with a greater identifier no. When we do rmmod on that module, the entry from /proc/scsi/scsi wipes off but still the counter of scsi identifier no. doesn't decreases. is is there any way to reset or decrement this counter so that next time when I do modprobe on scsi related module, it will assign no.s starting with 0 ? I found that during registering a scsi device, scsi_register() method gets value from "next_host" (which is a static int initialized to 0) and then increments next_host counter. Also, during scsi_unregister(), it decrements next_host counter. rmmod internally calls scsi_unregister(). So, if it is true then why the scsi host id. doesn't decrement during rmmod?

I've just put together a Centos 5.2 system using an old Future Domain SCSI card which would allow me to hook up an external DAT drive. On its BIOS screen it advertises itself as an AHA-2920 which should be handled by the aic7xxx module. However, the module doesn't even get loaded unless I force it in /etc/rc.modules and even then it doesn't pick up the card.

In my understanding, the way /proc/scsi/scsi gets populated, /proc/paritions also gets populated in the same fashion. i.e. the description for first entry of /proc/scsi/scsi can be seen in the first entry of /proc/partitions and same for rest.
So, With this assumption, in my project, I used to relate first entry of /proc/scsi/scsi with first entry of /proc/partitions to get its total size and same for all entries.
But, I observed some differences in following scenario, where
1) The first 4 entries in /proc/scsi/scsi are SAN luns attached to my system and for which the actual device names in /dev/ are sda,sdb,sdc and sdd.
2) The last 4 entries are the internal HDDs on same system. In /dev/, their respective device names are sde,sdf,sdg & sdh.
(Output attached at end of the thread)
But in /proc/partitions, the device order is different.
You can see their respective sizes in /proc/partition output as well.
So, my question is, in this particular scenario, I can't relate the first entry of /proc/scsi/scsi with first entry of /proc/partition. i.e. scsi0:00:00:00 is not /dev/sde, because it is actually /dev/sda.
It seems that my assumption is wrong in this scenario.
Is there any way or mechanism to figure out actual device name for an entry in /proc/scsi/scsi in /dev/ directory?
How can my application should relate /proc/scsi/scsi entries with their respective device names and sizes?
When I enter "cat /proc/scsi/scsi" I'm returned with "cat: /proc/scsi/scsi: No such file or directory". I've tried this on two different installs on two different machines.

I have Ubuntu 9.10, which I just now installed on my Dell Dimension 3000. The computer has all of its USB ports working perfectly; tested in Windows. I plugged in my SMC USB Ez Connect g wireless adapter, and it isn't even recognized by the system. I used lsusb, and nothing except the USB keyboard and mouse shows up. Every time I boot or shut down, I get tons of errors saying that it's "unable to enumerate USB device on Port...," then the port number of whichever port I plug the wireless adapter into. I've tried using ndiswrapper, and have completely installed the Windows drivers using that (which were the same ones that worked perfectly in Windows XP Pro). I've tried looking into compat-wireless and Linux Wireless, and have successfully installed the zd1211rw drivers and everything. The drivers install completely and work, there is just no hardware present, or so it says. This is what the terminal says when I type dmesg, and also part of what shows up on booting and shutdown:

I hope I've given enough information. Oh, and I downloaded Ubuntu a few days ago from their website, burned to a CD-R, installed, and downloaded all updates that it asked me to. Other than that and the ndiswrapper and driver installation, I've done nothing on the system.
I have an HP Pavilion dv5 1002nr laptop running Vista. I decided to install Ubuntu using the windows installer, which did install well, but I decided that it wasn't for me, and uninstalled it. Now, my wireless adapter which is a Atheros AR5007 802.11b/g can see the network, find networks by itself, and is supposedly installed correctly according to Vista, cannot connect to any networks at all despite being able to see them and acquire a signal strength. Up until installing Ubuntu I have never had an issue like this. Other devices have no trouble connecting to this network, and I am currently using a Netgear wireless usb dongle to connect to the very network that my Atheros can not connect to.

I felt the urge to build my own "Incredible PBX" system, and in the process downloaded pbxinaflash-i386-5.4.iso which is based on CentOS 5.4. The PC that I'm using is an old desktop, and the onboard ethernet adapter is not working, so I installed Trendnet PCI Adapter (te100-pciwn h/w : 2.2 R), which used to work greatly under Windows XP. Since my on-board ethernet adapater doesn't work, I disabled "eth0" device, and I modified eth1 device to load during boot. But, for whatever reasons, eth1 fails to get the IP address. I thought the driver that is part of CentOS 5.4 may not be working, so I thought of building the driver from the files provided in the CD (that came with TrendNet adapter box).. and unfortunately my attempts to build the driver have also failed.
Following files are attached in the zip file
- basedata.R3721 (info collected by ./getinfo.sh all )
- Directory 2.2.X has "te100.c, makefile, kern_compat.h copying.txt" (These files came with the Trendnet CD)
- errors (makefile errors when tried to build te100 driver)
From what I understand, TrendNet TE100-PCIWN is based on "Realtek Semiconductor Co., Ltd. RTL-8139" chipset. How to get my ethernet adapater (eth1) connected to internet.

I recently tried to install Crunchbang on my IBM Thinkpad T20 laptop. Everything went OK as far as I can tell (I still have to adjust acpi and display settings), but I cannot get my laptop to connect to the internet via wireless (wired connection works fine). I've done a good deal of searching online, and I realize that my wireless adapter (wpc54gs, bcm4318 chipset) is problematic in linux, and that b43-fwcutter is typically required. I did install b43-fwcutter, and it seemed to install OK, but nothing subsequently happened when I opened networkmanager. I'm not sure at this point if my problem is that I don't know how to configure any wireless adapter in crunchbang, or if it is that my particular adapter is not being recognized.
